I recently upgraded my 71 nova to power discs in the front. At the time I didn't paint the new master before installation and it is now in the car. Any type of paint I can put on it that will protect it from rusting? There is already a light coat of rust on the master, but that can be removed easily enough with just a small wire brush. I was thinking about painting some sort of rustolium primer on the master and follow up with some rustolium paint. I'm not sure if that will hold up anymore to brake fluid though.
